. IVINFIELD O. GUNOKEL, OF TERRE HAUTE, INDIANA.

BOILER FEED-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 404,400, dated J ulie4, 1889.

Application filed July 26, 1888. Serial No. 281,082. (No model.)

To all whom it may concern:

Be it known that I, WINEIELD O. GUNcKEL, a citizen of the United States,residing at Terre Haute, in the county of Vigo and State of Indiana,have invented certain new and useful Improvements in BoilerFeed-Regulators; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to boiler feed-regulators; and it consists in thenovel construction and combination of the parts hereinafter fullydescribed and'clailned.

This invention consists largely of improvements in the regulators forwhich I have made applications for Letters Patent on March 2,

1888, Serial No. 265,901, and May 4, 1888, Serial No. 272,837.

The drawing shows a vertical section through the feed-regulator.

A is the pipe through which the feed-water is pumped into the regulator,and B is the pipe through which the water passes from the regulator intothe boiler.

G is the casing of the feed-regulating valve D, which Works within theconical seat E.

F is the casing for the float, and G is a stem which connects thefloat-casing with the regulating-valve casing. The seatE is providedwith annular orifices 6, so that the valve D is balanced against lateralpressure. The seat E has a flange e at the top, which is secured betweenthe flanges of the casing O and stem G. The valve-seat E is providedwith a solid bottom f, and g are projections for the valve to rest upon,so that the water may pass under it.

The conical valve D is hollow and openendcd. It is preferable to acylindrical valve, because it is absolutely frictionless in itsmovements while regulating the amount of water passing through it, andthe small amount of downward pressure upon it when closed is only justsuflicient to prevent it from sticking.

H is the safety-valve, which is preferably a spring-valve, as shown, andh is the overflowpipe which returns the surplus water to the supply-tankof the pump. The safety-valve is attached to the inlet-pipe A in theusual manner.

F is the float, provided with the float-lever f, and (Z is a rodprovided with a yoke d, which connects the said float-lever with theconical valve D. The float-lever is pivoted to the pin '7; of theadjustable stem 1', which passes through the stufling-box j, and isoperated by means of the screwed spindle 7" and connecting-piece 7c. Theconnecting-piece is secured to the end of stem 6, and has the end ofspindle j journaled in it. Ascrew-threaded boss k is provided on thecasing for the said spindle to engage with.

I is the pipe which connects the top of the float-casing with thesteamspace of the boiler, and J is a pipe which connects the bottom ofthe float-casing with the water-space of the boiler. The adjustablefulcrum for the floatlever permits the water-let 'el of the boiler to bevaried several inches at pleasure without moving the entire regulator.

K is a partition between the internal space of the float-casin g and thewater-space above the regulating-valve.

L is a hole for the passage of the stem (1. The object of thusseparating the float-casing water-space from the water-space above thevalve is to insure still water for the floatto work in, the hole L beingtoo small to allow the disturbance of the water in the space above thevalve, due to the action of the pump, to be communicated to the waterunder the float.

The feed-pump is caused to operate continuously, and when the floatrises it decreases the annular passage between the conical valve D andits seat, so that the surplus water is forced through the safety-valvedown the overflow-pipe.

M is the steam-supply-valve casin g to the upper part of thefloat-casing.

M is a cylindrical balanced steam-supply valve provided withsteam-passages m.

N is a cylinder in which the valve M works, and n are annular passagesin said cylinder which communicate with the said steam-passages in thevalve. The valve M is connected to the upper end of the stem d,

secured and n is an opening in the top of the floatcasing, which permitsthe steam to have free access to the interior of the valve.

0 is the steam-supply pipe for the pump, which pipe is connected to thecasing M. The pump receives all its steam through the float-casing andsaid pipe 0.

hen the float rises and a portion of the feed-water is forced throughthe safety-valve, the valve M is also moved to partially cut off thesupply of steam to the pump. This, of

course, makes the pump work slower and saves it from wearing out soquickly.

\Vhat I claim is- 1. I11 a boiler feed-regulator, the combination, witha conical regulating-valve working in a seat provided with orifices forthe passage of water, of an outer casing for said valve and its seat, afloat operatively connected to said conical valve, a float-casingconnected to said valve-casing, inlet and delivery pipes upon oppositesides of the regulating-valve, and a safety-valve secured upon theinlet-pipe, substantially as and for the purpose set forth.

2. In a boiler feed-regulator, the combination, with an open-endedconical regulatingvalve, of a valve-seat provided with lateral orificesfor the passage of water, and projections on its bottom for the saidvalve to rest on, of an outer casing for the said valve and its seat, afloat operatively connected to said conical valve, a float-casingconnected to the said valve-casing, inlet and delivery pipes uponopposite sides of the regulating-valve, and a safety-valve secured uponthe inletpipe, substantially as and for the purpose set forth.

3. The combination, with the water-regulating valve of a boiler-feeder,of the float provided with a lever and operatively connected to saidvalve, a fulcrum-stem for the said lever passing through thefloat-casing, a connecting-piece secured to the end of said stem, and arevoluble screwed spin d le engaging with a stationary screw-threadedprojection and journaled in the eonnecting-piece for adjust ing thefulcrum of the float, substantially as set forth.

at. In a boiler feed-regulator, the combination, with a water-regulatingvalve provided with a stem and a float operatively connected to the saidstem, of an outer casing for the said valve, water inlet and deliverypipes upon opposite sides of the valve, a casing for the float connectedto the steam and water spaces of the boiler, and a partition providedwith a hole for the valve-stem and arranged between the water-spaceunder the float and the water-space above the regulating-valve, wherebythe float may rest in still water, substantially as set forth.

, 5. In a boiler feed-regulator, the combination, with awater-regulating valve prox'ided with inlet and outlet pipes, and asafety-valve upon the said inlet-pipe, of a float provided with apivoted lever and Working in a casing above the said water-valve,abalanced steamsupply valve for the pump working in a cyl inder on topof the float-easing, both valve and cylinder being provided withorifices for regulating the passage of steam from the floatcasin g, anda stem connecting the said steam and water valves with the float-lever,substantially as and for the purpose set forth.

(5. In a boiler feed-regulator, the combination, with a water-regulatingvalve provided with inlet and outlet pipes, and a safety-valve on thesaid inlet-pipe, of a float provided with a pivoted lever, asteam-supply valve for the pump, a stem connecting the said steam andwater-valves with the float-lever, and easi n gs inclosing the saidwater-valve and float and having their internal spaces separated by apartition provided with a small hole for the passage of the valve-stein,whereby the float may work in still water and the steam-valve receivedry steam direct from the upper part of the float-casing, substantiallyas set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
